If those recommendations don't get to Congress by 2010 -- a distinct possibility -- that could raise a new and thorny obstacle that could further mire the projects in federal politics. That's because Congress in 2007 enacted a provision allowing all projects recommended by the corps before 2010 to be put into a fast-track approval process, which requires a vote after just 45 days.

Congress could likely approve the projects en masse -- and quickly -- greatly accelerating the start of construction. But if the fast-track rule expires, the state could be forced to lobby for each individual levee or coastal restoration project, with no defined timeline for approval of any of them.

That concern, along with deep frustration over the delays, poured out of nearly three dozen legislators Tuesday as Gov. Bobby Jindal's coastal czar, Garrett Graves, briefed them at a joint meeting of five legislative committees.

The details of the continuing delays -- combined with the fact that corps officials passed on an invitation to appear before the committee -- prompted one legislator to suggest sending the Legislature's sergeant-at-arms to New Orleans to fetch top corps officials. Another suggested that the state cut off natural gas to the rest of the country in the middle of winter.

"We're at the point where we have to take drastic measures to make this nation understand how important our communities, our fishermen, are to the rest of the nation," she said. "If we were able to cut (natural gas) today for the rest of the weekend, it would send that message."

Graves, director of the Office of Coastal Protection and Restoration, told state politicians Tuesday that Louisiana's future is threatened by the continuing delays in completing a plan to protect coastal communities from storm surges created by worst-case hurricanes.

The corps has repeatedly failed to meet congressional deadlines for completing the Louisiana Coastal Protection and Restoration Study, which is now more than a year late, he said. Senior corps officials turned down a request to testify about the delays before the unusual joint meeting of the House and Senate committees on Transportation, Highways and Public Works, House and Senate committees on Natural Resources and the Senate Select Committee on Coastal Restoration and Flood Control, said Rep. Nita Hutter, R-Chalmette, chairwoman of the House transportation committee.

"We requested the opportunity to brief the committee after the LaCPR Technical Report has undergone the final reviews required by federal law and regulations," said Maj. Timothy Kurgan, a spokesman for the corps' New Orleans district office, when asked why corps officials did not attend the meeting. "We currently anticipate that the report will be forwarded to the National Academy of Sciences for statutorily required external peer review in March 2009," he said.

Graves said the corps told the state's congressional delegation in December that the study, now scheduled for completion in late June, will include a list of projects that Congress can authorize immediately. Both the project list and the environmental study were required by Congress in legislation ordering the study, he said.

Even if completed by June, it remains unclear how long it will take for the study to be delivered to Congress, Graves said, because it must then await approval by senior Army officials.

Congress appropriated $23 million to complete the study, which would identify a much higher level of protection for New Orleans than the improvements currently under construction. Current construction aims to protect the region from a moderate-strength hurricane with a 1 percent chance of occurring in any year, also referred to as a 100-year storm.

The new study was supposed to aim for protection from "the equivalent of a Category 5 hurricane" by combining higher levees, gates and coastal restoration projects.

The corps has been looking at projects that could protect some areas from 400-year storms, such as Hurricane Katrina, or larger, 1,000-year storms. Parts of the coast would remain either unprotected or protected by smaller levees.

But after initially focusing on a list of projects that the corps and state had quickly identified, including many in the state's own master plan, the corps moved into "an era of stonewalling" during the summer of 2006, said King Milling, chairman of the Governor's Advisory Committee for Coastal Protection, Restoration and Conservation.

Rather than identifying and endorsing projects, the agency adopted a recommendation to create a complex "risk-informed decision matrix," causing considerable delays. The decision matrix, however, would produce no decisions; the agency instead merely identified five groups of alternative plans for five different regions along the coast.

Milling said that change of strategy was ordered by the White House Office of Management and Budget, rather than the corps' New Orleans District officials in charge of the study.

"This has to do with money and the influence of power," Milling said.
